I find it strange that you guys are getting so much hiss. I get only a very small amount using my JH5 which are really sensitive, none using ASG-2.

Beats me. Ibasso wasnt much help. If it matters, i do not listen to a lot of rock, hiphop, pop that might mask the hiss. All my files are flac. I am on 1.2os. I was thinking of trying a 75ohm resister 3.5mm but not sure what that would do to the sound of the 4.ai.

I was under the impression that the DX50 would be a one-stop shop for IEM users...I was wrong.

Even if the amp hisses slightly with the iems, as soon as I crank the volume I find the music covering the hiss so it just sounds worst than it really is. It also depends on the pair, one pair I don't have the issue while the other is a bit apparent.

Vsonic Gr07 - Spacious, slightly warm sound. The treble can be a little harsh at times, but can be EQ'd. The gr07 makes for a nice budget combo with the dx50. There is no noticeable hiss with the gr07s thankfully.

I don't have the BE but the mkii is great with the dx50. If the BE doesn't have any treble or sibilance issues than it would probably be an even better combo with the dx50 considering that the dx50 is fairly neutral or perhaps slightly bright to some.
